One word of caution, Gary, if the CATV splitter is a transformer type,
rather than resistive it may of have enough low-frequency response for 160
m! Check around with RS and your local electronics stores for 50 ohm 2-way
splitters. Those are generally resistive and have frequency response from DC
up to a GHz or so. Some of the TV stuff is transformer coupled.

Subject: Topband: Passive Receive Antenna Splitter
Can anyone point me to a design for a splitter for sharing a Beverage
antenna between two receivers? This is for Field Day so these are not
optimized Beverages by any means.
Just want to allow the 80/40M stations to share antennas. Nothing fancy.
My thoughts are to just use a CATV "2-Way" splitter at the output of the
Beverage matching transformer and run separate feed-lines to each radio.
I'm pretty sure these things work down to 1 MHz but have not measured them.
I can use the pre-amp in the radio (K3) to compensate for the loss.
Thoughts?
